I TYPOGRAPHICAL MACHINE.

- Application filed April 17,

This invention relates to typographical machines, such as linotypemachines, wherein the circulating matrices in a composed order for alinotype are transferred from an assembling elevator into. a receivingchannel of a vertically movable first elevator, which presents it to amold to enable the type bar or slug to be cast therefrom.

In machines of this class various sets of matrices are employed, as, forinstance, matrices bearing .a single character; matrices bearing twocharacters located at different levels thereon, matrices having largeface characters, known as head letters or head 1 characters, for castinga slug having an extended width over a single line Width. Therefore,different matrix supporting positions are provided, whereby the matricesmay be composed and maintained at upper or lower levels as desired, tolocate the selected characters in operative position.

In the use of head letter matrices as having large face characters, itis a practice to assemble them at the usual or lowest 2 level in thefirst elevator and provide means for positioning the first elevator toan auxiliary position, or level corresponding to an upper level, withrespect to a mold, in order to enable a type metal from the mold toproperly reach all portions of such character. The positioning of thefirst elevator to an auxiliary position being generally accomplished bythe use of a socalled fill ng piece, which when in operative positionfunctionsto arrest the movement of the first elevator when it reaches-=that point in its descent at which the matrix will occupy a properposition with respect to the mold.

The filling piece also functions to control a socalled vise-automaticfor stopping the machine in the event that the matrices were notproperly positioned relatively to the mold, such control being alsoefiective when the first elevator descends to its normal position orpoint.

After the matrices in the first elevator have been properly positionedwith respect to the mold, the mold moves laterally against the matrices,after which the casting is made.

As the throwing in of the filling piece is under manual control, ithappens that the operator inadvertentlygfai'ls to make said throwin, sothat the assembled matrices in the 1924. Serial No. 707,244.

first elevator are not-sustained in their proper mold registeringposition, resulting in the improper representation of the matrix line tothe mold and hence producing a squirt, or causing damage to the parts orboth.

lVith the present invention, when a line casting is to be made, whichrequires the first elevator to be sustained in an auxiliary position orlevel, the first elevator is automatically elevated or adjusted to aposition for appropriately bringing the-matrix line to registeringposition with the mold, the mechanism for adjusting the first elevatorbeing actuated by the mold in its movement toward the matrix line.

As a different mold is required for casting head letters from that ofgeneral characters, the machine is provided with a plurality of moldsmounted on a disk, orrotated carrier, whereby the molds are selectivelybrought to a functioning position. Therefore, the mold carrier isprovided with means for cooperating with the mechanism for elevating thefirst elevator, when the head letter mold is moved into its operative position, and adapting first elevator auxiliary positioning mechanism tobe out of commission when the various other molds on the carrier areselectively brought to operative position. Therefore, an object of theinvention is to provide means for automatically moving the firstelevator carrying type matrices in a composed line, to an auxiliaryposition sustaining the matrices in an appropriate level for moldregistry and cooperation therewith.

Another object of my invention is to pro-, vide for a machine of theclass specified, a lever mechanism actuated by the forward motion of themold, which will raise the first elevator a sufficient amount to causeit to cooperate with the mold in question.

Other objects and certain advantages will appear in the description ofthe drawings forming a part of this specification, in which:

The present invention is applicable genorally to typographical machines,wherein matrices may be assembled at either of two levels, andpositioned at either of two levels, in front of a mold adapted to castslug or type bart-herefrom.

In machines of such capacity, the improvoment can be easily applied tothe connnereial machines as an attachment; therefore, themachineorganization not distiu'hed or its general operationinterferedwith. The first elevator for casting head letters permit-ted to descendto its normal position or level for functioning or controlling the 50*called vise automatic, which is in advance of tlle timed movement at themold toward the composed line oi matrices carried lay the firstelevator, the first elevatorbeingelevated to its auxiliary posit ionubylever oeviees actuatedby the mold mechanism in its move ment toward thematrices. This, therefore, causes no interference in the generaloperation ofthe machine or the satet y" device em ployed for-itscontrol* and avoids any manual control for the auxiliary positioning ofthe first elhvator.

Referring'to the drawings 1 indicates the conventional type UTE moldcarrier for supporting a mold 52 or a plurality of molds spaced aboutthe carrier. The carrier rotatable for bringing the several moldsmounted upon the carrierselectively to an operative position. The moldbod below the mold cavity or cell 3 is provided with grooves las upperand lower, to respectively receive the lugs 5 of the matrices assembledin the. jaws of the lirst elevator 6. The elevator is slidingly engagedwith the vise cap of the vise frame i". The mold and itscarrier, firstelevator and vise frame are of standard commercial structure and theiroperation "\VGlllIliOWll in the art so that more specific illustrationand description thereof need not be made herein for the purposes of thepresent invention;

Ilevermeclianism for raising the first elevator to its proper level issecured to the Block Son the vise frame 7. In this position, the leversdo not interfere with other parts of the mechanism being mounted uponthe block and securely attached to the vise frame.

This main lever mechanism comprises a toggle, lever, operated by a rodattached at its central pivot. More specifically, I mount upon a plate10, the surface of which is eas -s4.

parallel to the line of motion of the mold disc, two spaced plates 11,12, each provided with a semi-cylindrical recess 13. These roceases areopposite to one anothon, and in them are positioned the two members 14:,15, oi my toggle lever. The ends 16, of these members Ll, T5, aresemi-circular and fit intothe reo as 13 coopeatiug with them to form endpivots for the toggle. The lower one of these plates'th is secured tothe plate 10 stationarily and the upper 12 is hinged, thus constitutingsaid upper plate itself a .econd lever. This form of pivot is foundlight, staunch and economical, but othen forms of pivots are usable andare llltBlldhCh to be included withini the scope of, this lllr vention.

The rod 1"? WlllClLflChUitiiGS-hlKMtOgglUlGVGU is provided with beveledouter edges 18, which cooperate \vi thibearing attaclln'ients 19 to theplate 10 which foiun guides font/he rod. Any pivotal: connection betweenthis. red and the two members oh the toggle is; suilicient, but I preferthat the nod shouldabe:

My toggle mechanism isiso. positioned: on the machine that it i:nyn'actioal toxtransmit: the upward motion ol. the plate ltl aotuated bythe toggle lever, innnediately r to theiirst elevator (S, but 1 acconi is11 this result by inter 'iosing a; third lever 25;. pivoted to the visefran'ie T, above the second levon l2. and adapted to he actuated by it.l] lind' itvery, practical to screw thepivotal mountingiflfl into thatopening cm the visa teams 7,. the upper portion of which is filledibythe bolt (not shown) which secures the vise ea :2! to the visa frame. Onthe other-u en of. this third lever 25 is w a lifting rod, 28iwhichextends upwardly through the vise" cap. 27 and terminates undorthe head29*oftthe first cleva'torG, and is thus adapted toraise the same.

A connection between thisrli'lting rod;28 and the third lever 25 is adjustable". Ilhrough theond of the lover is screwed athread? ed sleeve 30which securedby a. look not 31 on the undersideofsaidwlever; The lift.-ing rod 28 is provided with a dovvnvvardlf extending pin portion 32*,adapted. toienter this sleeve, but to lit loosely to compensate for theslight dill erence in the tllll-BCiIlGHSlH motion of the lever and thelifting rod.

When my attachment is used, the mold disc moves forward, engages therod, which operates the toggle, lifts the second lever, which in turnraises the third lever to which is attached the rod which directly liftsthe first elevator, thus, whether the filling piece (not shown) is usedor not, my mechanism positions the first elevator at the proper heightso that the matrices properly'align with the mold slot.

The inherent characteristic of a toggle lever, that the rapidity ofmotion decreases as the 180 point is reached, causes rapid motion of thefirst elevator until approximately the correct height is attained, andthen relative slow motion as the mold disc comes forward and fits itsown groove over the lugs on matrices.

When the mold carrier is rotated to move the mold for the head lettersout of commission the stud 22 is moved out of engagement with the rodwhereby the lever mechanism is inactive, in any forward movement of themold carrier.

Having described my invention, I claim:
